Devices for orally administering treatment liquids to animals

Abstract

A device for administering to animals a treatment liquid stored in a container, the device comprising a hollow loop serving as a flow conduit between the container and a flexible nozzle mounted on one side of the loop adapted to direct a jet of the liquid toward the back of the animal's throat. The loop has a geometry close to that of an equilateral triangle, the corners of which adjacent the side which carries the nozzle being rounded whereby the loop may be clamped very firmly on the nose of the animal without inflicting pain.

I claim: 
     
       1. A device for administering to animals a treatment liquid, said device comprising: A. a container to store the treatment liquid;   B. a hollow loop formed of a single piece of tubing and having a geometry close to that of an equilateral triangle whose two inclined sides coverge toward a vertex;   C. a nozzle mounted on the third side of the loop at a positon opposite to the vertex thereof and adapted to direct a jet of the liquid toward the back of the animal's throat, the corners of the loop adjacent said third side being rounded with a relatively large radius sufficient to avoid cutting the lips of the animal to define a bit having a pear-shaped space in the area bounded by the sides which is compatible with the morphology of the animal being treated, whereby the loop can be clamped very firmly on the nose of the animal without inflicting pain; and   D. means coupling the vertex of the loop to the container, said loop serving as a conduit to conduct the liquid from the container to the nozzle, said means being constituted by a cylindrical boss at the vertex, which boss has a threaded bore adapted to receive one eternally-threaded male nipple of a coupling having a second externally-threaded male nipple which is coupled to the container.   
     
     
       2. A device as set forth in claim 1, in which the container is a bottle having a flexible wall, the bottle having a cap screwed onto its neck, which cap is coupled to the second male nipple, and a lever clamped to the bottle, the lever having an inwardly curved portion which engages the wall, and which when the lever is operated, deforms the wall to squeeze liquid from the bottle. 
     
     
       3. A device as set forth in claim 2, wherein the lever is provided with a sleeve of flexible material which is shiftable along the lever to cover the curved portion thereof and thereby increase its thickness to enchance the deformation of the wall. 
     
     
       4. A device according to claim 2, wherein said cap is provided with an axial hole to receive the second threaded nipple, a nut being screwed on the second nipple and resting, via a washer forming a sealing joint, against the inner face of the bottom of the cap. 
     
     
       5. A device according to claim 1, further including a cock interposed between the container and the loop, said cock having at one of its ends a threaded female bore adapted to receive the second threaded nipple of said coupling, and at its other end a threaded nipple. 
     
     
       6. A device according to claim 5, wherein said container is a can of large volume provided with a threaded nipple, and said loop is connected to the said can by a flexible pipe, one of whose ends is provided with a first female coupling screwed onto the nipple of the can, the other end of the pipe being provided with a second flexible second female coupling screwed onto the threaded nipple of the cock.
